<h1 class="topictitle1">Step 5: Performing Backup</h1>
<div><p>Before performing backup, you need to associate the resources to be protected with a specified SLA. The system protects the resources and periodically executes backup jobs based on the SLA. You can perform a backup job immediately through manual backup.</p>
<div class="section"><h4 class="sectiontitle">Prerequisites</h4><ul><li>Before the backup, you need to ensure that the pexpect package (pexpect 3.2 recommended) has been installed on the agent host. For details about how to download and install pexpect, see "Installing pexpect" in the <i><cite>OceanProtect DataBackup 1.5.0-1.6.0 ProtectAgent Installation Guide</cite></i>.</li><li>Before the backup, ensure that GBase 8a databases are running properly and the network connection of each node in the cluster is normal.</li><li>During the backup, the passwords of the GBase 8a agent host and database users cannot be changed.</li></ul>
</div>
<div class="section"><h4 class="sectiontitle">Context</h4><ul><li>During the execution of a manual backup job, parameters (except <span class="uicontrol"><b><span><strong>Automatic Retry</strong></span></b></span>) defined in the SLA, such as <span class="uicontrol"><b><span><strong>Rate Limiting Policies</strong></span></b></span>, <span class="uicontrol"><b><span><strong>Job Failure Alarm</strong></span></b></span>, and <span class="uicontrol"><b><span><strong>Source Deduplication</strong></span></b></span>, take effect.</li><li>If a replication or archive policy has been defined in the SLA, the system will perform replication or archiving once based on the SLA when you perform manual backup.</li></ul>
